Get Jaccard similarity coefficient scores — get_jaccard

Get the Jaccard similarity coefficient scores for one or more nodes in a graph.

Usage

get_jaccard_similarity(graph, nodes = NULL, direction = "all", round_to = 3)

Arguments

graph: A graph object of class dgr_graph.
nodes: An optional vector of node IDs to consider for Jaccard similarity scores. If not supplied, then similarity scores will be provided for every pair of nodes in the graph.
direction: Using all (the default), the function will ignore edge direction when determining scores for neighboring nodes. With out and in, edge direction for neighboring nodes will be considered.
round_to: The maximum number of decimal places to retain for the Jaccard similarity coefficient scores. The default value is 3.

Value

A matrix with Jaccard similarity values for each pair of nodes considered.

Examples

# Create a random graph using the
# `add_gnm_graph()` function
graph <-
  create_graph(
    directed = FALSE) %>%
  add_gnm_graph(
    n = 10,
    m = 15,
    set_seed = 23)

# Get the Jaccard similarity
# values for nodes `5`, `6`,
# and `7`
graph %>%
  get_jaccard_similarity(
    nodes = 5:7)
#>       5     6     7
#> 5 1.000 0.286 0.400
#> 6 0.286 1.000 0.333
#> 7 0.400 0.333 1.000
